The HathiTrust Research Center (HTRC) provides an infrastructure to search, collect, analyze, and visualize the full text of nearly 3 million public domain works within the HathiTrust and is intended for nonprofit and educational researchers. It is a collaborative research center launched jointly by Indiana University and the University of Illinois, along with HathiTrust, to help meet the technical challenges researchers face when dealing with massive amounts of digital text. It develops cutting-edge software tools and cyberinfrastructure to enable advanced computational access to the growing digital record of human knowledge.
The HTRC builds tools and services for scholars to perform research using data from the HathiTrust Digital Library. The Center is breaking new ground in the areas of text mining and non-consumptive research, allowing scholars to fully utilize HathiTrust content while preventing intellectual property misuse within the confines of current U.S. copyright law.
HathiTrust Research Center creates tools for researchers to analyze the text of content in the HathiTrust Digital Library. These tools make it easier for researchers to perform text analysis and many have easy to use interfaces.
An unrestricted dataset of metadata and word count for each page in the HathiTrust Digital Library.
The HathiTrust Bookworm allows for the searching of lexical trends millions of volumes in HathiTrust over time. Search by date, publication country, language, words per volume, number of words, or resource type to see how often words have been used.
HTRC Algorithms are web-based, click-and-run tools to perform computational text analysis on volumes in the HathiTrust Digital Library. The algorithms can help you explore, analyze, and visualize public worksets or those you have created.
A system of a secure computing environments for performing researcher-driven text analysis on the HathiTrust corpus. All users may access public domain items but access to items in copyright are restricted to member-affiliated researchers.
Experiment with HTRC in-development and beta tools. Some tools may eventually be integrated into HTRC's suite of tools, or they may be taken down. Some tools may require experience with programming.
HTRC worksets are user-created collections of HathiTrust volumes to be treated as data and analyzed using HTRC tools and services. Worksets are curated by researchers, and they can be shared and cited to improve reproducibility.
HTRC releases research datasets to facilitate text analysis using the HathiTrust Digital Library.
What are collections?
HathiTrust Digital Library allows users to create lists or collections of items in the HathiTrust. These collections can be searched independently of the rest of the repository and are a great way to gather related resources together. Each collection can be kept private or made public so that other users can view them. HathiTrust has many different types of collections publicly available. Some featured collections could include Women Composers Collections, Records of the American Colonies, Islamic Manuscripts, and Ancestry and Genealogy.
Types of Collections
Without logging in, you can create temporary collections. These collections have all the same functionality of permanent collections, but are only available until the end of the browser session.
If you are logged into a institutional account, you can create permanent collections. Permanent collections will be available any time that you are logged in and you can keep adding items to grow the collection. These collections can be shared via many different social media platforms and can be made public so they can be found on HathiTrust.
Creating and Adding to Collections
To create a collection:
To add a work to a collection:
HathiTrust collections may be used to save books for future reference; search across selected volumes; share with others; or to download metadata for selected volumes.
For more information see:
Clicking on the Collections tab at the top of the homepage brings up a list of all the collections created and made public by HathiTrust users. There are a variety of ways to sort these public collections, including by number of items, title, and owner. You may also search public collections by keyword. There is no advanced search option for collections.
